Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This revised standard adopts ISO 17052.2007 Determination of thermal desorption "raw rubber residual monomers and other volatile low molecular weight compounds
(Dynamic headspace) capillary gas chromatography "(in English).
This standard and ISO 17052.2007 as compared to doing the following editorial changes.
--- The "this International Standard" be replaced by "this standard";
--- Remove the ISO 17052.2007 directory, foreword, introduction, references;
--- The Normative references to international standards in our respective national standards;
--- All "ppm" to "μg/g";
--- For ease of use, to modify the contents of the original Appendix C and adjustment to Chapter 9;
--- Added Appendix C (informative) "GC conditions."

Raw rubber residual monomers and other volatile low molecular weight
Determination of dynamic headspace compounds - Gas Chromatography
1 Scope
This standard specifies a dynamic headspace (thermal analysis) - capillary gas chromatography raw rubber low residual monomers and other volatile
The method of molecular weight compounds, including a general method applicable to all types of raw rubber and two specific types of raw rubber (attached
Appendix A and Appendix B).
This standard applies to raw rubber residual monomers, solvents and low molecular weight determination of boiling point between butane and dodecane between compounds.
Determination of the standard low limit of 1μg/g.
